Alexander Ostermann

Prof. Alexander Ostermann is a Full Professor of Numerical Analysis and Scientific Computing at the University of Innsbruck, leading the Department of Mathematics and the Research Area Scientific Computing. He holds roles such as Dean of the Faculty of Mathematics, Computer Science, and Physics, and editorial board memberships in journals like GAMM Mitteilungen and Advances in Applied Mathematics and Mechanics. His research focuses on numerical methods for PDEs, exponential integrators, splitting techniques, and high-performance computing. He has supervised numerous PhD/Master’s students and collaborates internationally on projects like EuroCC Austria and Vienna Scientific Cluster.

Education: Dr. rer. nat. (1988) and Mag. rer. nat. (1984) from Universität Innsbruck. Professional milestones include roles at the University of Geneva and extensive administrative leadership in academic governance.

Research Interests: Development and analysis of numerical methods for time-dependent PDEs, including exponential integrators, splitting methods, and error estimation under low-regularity conditions. Applications span computational physics, fluid dynamics, and quantum mechanics.

Publications & Impact: Over 100 peer-reviewed articles, including work on Fourier integrators for the nonlinear Schrödinger equation and dynamical low-rank approaches. His methods are applied in high-performance computing for complex systems like Vlasov-Maxwell equations.

Advising & Teams: Advisor to PhD students in numerical analysis and computational mathematics. Collaborates with teams on projects involving scientific computing frameworks and software development (e.g., avaflow for mass flow simulations).
